On Sunday, overall moisture levels are expected to increase, and surface winds will become more SW as the low moves north towards the Carolinas. This pattern favors thunderstorm activity on the eastern side of Florida. "On launch day, the main concern will be the conditions at the time of MST Rollback. During the launch window, any activity should be offshore, with the main concern being remnant cloud cover and possible light rain."
